Welcome, Lifehackers, to this week's Hacker Challenge! Since the holidays are coming up, we're actually giving you two whole weeks to prepare your submission and send it to us. That gives you plenty of time to think about it and get it submitted. Our editors pick the best submissions and our favorite will win an autographed copy of the Lifehacker book!

Now, it's your turn. We want to see your best DIY mouse or keyboard hack. This can take the form of a soft hack (such as a great AutoHotkey script) or, even better, a hardware hack that makes your mouse or keyboard do something it couldn't do before.

How to Submit Your Entry

Make sure to follow these instructions when you submit your entry:

Post your entry below or send it to challenge@lifehacker.com with the subject Hacker Challenge: Mouse or Keyboard Hack. If you post your entry below and need to include more than one image, just reply to your own comment or host your extra pics on a free, quick image-hosting site like imgur and link out to your gallery.

We will accept entries up through Sunday night, January 6 at 11:59pm Pacific Standard Time

We will showcase the best submissions and announce our favorite Monday, January 7.

Break out your tools and get to work! And don't forget to check back for new challenges every week.
